اطہرؔ صدیقی(۱۹۳۵ء۔پ) کا اصل نام محمدیسیٰن صدیقی اور اطہرؔ تخلص کرتے تھے۔ آپ چوہان حال برہان پور تحصیل پسرور میں پیدا ہوئے۔ آپ معروف شاعر پروفیسر حفیظ صدیقی کے بھائی تھے۔ حفیظ صدیقی کی راہنمائی میں اطہر نے زمانہ طالب علمی میں شاعری کا آغاز کیا تو ان کا کلام ملک کے معروف ادبی رسائل و جرائد میں شائع ہونے لگا۔(۹۱۶)
اطہرؔ کا پہلا شعری مجموعہ’’ کاکل غم‘‘ غزلوں اور نظموں پر مشتمل ہے جو۱۹۸۷ء میں شائع ہوا۔دوسرامجموعہ کلام’’ذوق سفر‘‘ کے نام سے ۱۹۸۹ء میں صدیقی پبلی کیشنز لاہور سے طبع ہوا۔ یہ مجموعہ غزلیات پر مشتمل ہے۔ تیسرا شعری مجموعہ’’آبرؤے غم‘‘۱۹۹۰ء میں صدیقی پبلی کیشنز لاہور سے شائع ہوا۔ یہ مجموعہ بھی غزلیات پر مشتمل ہے۔ چوتھا شعری مجموعہ ’’گردِ مسافت‘‘غزلیات اور نظموں پر مشتمل ہے۔
اطہر ؔصدیقی کی شاعری کا بڑا موضوع عظمت انسان ہے ۔وہ اپنی شاعری میں حضور ؐ کی ذات اقدس کے شیدائی نظر آتے ہیں۔ ان کے نزدیک حضرت محمدؐ کی ہستی عظمت انسان کی علامت ہے۔ اور وہی مثالیِانسان کا نمونہ ہیں۔انھوں نے نعت میں ہی نہیں بلکہ اپنی نظم اور غزل میں بھی عظمتِ انسان کی حقیقت کا اظہار کیا ہے:
ذرے ذرے سے پوچھ دیکھا ہے
-دشت در دشت کون رہتا ہے
5کون رہتا ہے لا مکاں میں اب
3کس کی رعنائیوں کا چرچا ہے

ƒاطہرؔ کی شاعری عزم و ہمت ،جوش ،جواں جذبوں ،جستجو اور بلند حوصلوں سے بھر پور شاعری ہے ۔وہ اپنی شاعری میں کہیں بھی پست ہمت نظر نہیں آتے۔ان کے ہاں جوش اور جذبات کی شدت قاری کے حوصلے کو بلند...
خطۂ بہاول پور کے چند مغربی اسفار(ایک نو آبادیاتی باشندے کی نظر میں) Where the western colonial powers have had a profound influence on other forms of literature, such a genre of travel journalism in the Bahawalpur region could not be safeguarded. The region is known for its civilization and culture, yet the rumors that have been written from Pakistan to Pakistan remain mournful that the tradition under the influence has stirred. Although the nature of the journals being written in the Bahawalpur region varied, the correspondents here discussed the impact that the west had given them. At the national level, the ambassadors sought for western couples and also showed an attitude of disregarding civilization and culture. At the national level, the ambassadors sought for western couples and also showed an attitude of disregarding civilization and culture. Travelling entrepreneurs separate from their country apart from a new angle and independent thinking, they seem to be lacking in the west. This difference can be seen even more clearly if domestic and international travels are taken into account.
The idea of starting this research project was to elucidate the development procedure of a novel biocompatible nano composite that is directly linked to the properties of natural bone in terms of its composition, morphology, mechanical properties and biocompatibility. These nanocomposites are composed of hydroxyapatite (HA) and whitlockite (WH) nanoparticles embedded in polymeric matrix and hydrogels.The fabrication procedures used are of common use including pre-treatment of nanoparticles and embedding into biopolymers such as Cyclic olefenic copolymer and CollagenPEGDMA hybrid matrix where effect of different loading ratios of HA nanoparticles and WH nanoparticles was investigated.Nano powders of HA were chemically synthesized under various processing conditions using surfactants with different charges and chain lengths such as CTAB (cationic) and SDS (anionic) surfactants were used in the synthesis procedures for regulating the nucleation and growth of the hydroxyapatite phase. The synthesis methods, mainly based on aqueous systems were used which are simple and can offer accurate control on the nano powders of various size and morphologies. The effect of different weight ratios ofHA nanoparticles and WH was evaluated after successful fabrication of nanocomposites by dispersing these nanoparticles in polymeric matrices. TOPAS/HA, TOPAS/WH and Collagen-PEGDMA/HA nanocomposites were successfully prepared and further characterized. Solution casting procedure was used to construct these nano composites. Effect of various weight ratios was investigated on physical, chemical and mechanical properties of the nano composites. These nano composites were characterized through Scanning Electron Microscopy, Fourier Transform Infrared Spectroscopy, Compression testing, Biocompatibility testing including cell culture of bone/cartilage cell lines, antibacterial test, biodegradability, and swelling characteristics. The morphology of nanocomposites has been investigated using Scanning electron microscopy and Atomic force microscopy. Compression testingwas performed on all type of nanocomposites to evaluate and optimize the mechanical strength. Cell culture wasperformedto evaluate thebiocompatibility ofthese nanocomposites onbone cell lines in case of TOPAS/HA and TOPAS/WH while cartilage cell lines were used in the case of COl-PGD/HA nanocomposites. Swelling and degradation characteristics were also evaluated. It was revealed from this study thet the compressive strengths of nano compositescan be enhancedwith the addition of nanoparticlesand optimized to make values comparable with the compressive strength of natural bone and cartilage tissues. In case of TOPAS/HA the increased values are185 % from 0.26 to 0.74 MPa at the concentration of 10 wt%.Whearas in case of PGD-16/HA, up to 10 wt%, strength is enhanced ~ 90 % from 9 to 17.3 kPa.In case of TOPAS/WH increase of 0.2MPa to 1.7MPa in strength at lower concentration of WH upto 10wt%has been experimented. The biocompatibility data of cell viability on the whole, is above 90% in all nanocomposites and the values are even higher than95%.In TOPAS/HA (10 wt%) exhibits the highest trend for cell viability of 99.9 ± , while in case of PGD-16/HA (10 wt%) the cell viability of hybrid composites is 100 % as comparedto the TCP control group while the cell viability values are around 95-100% in case of TOPAS/WH (10wt%). These results make these nanocomposites suitable for biomedical applications.
